Filed Dec. 17, 1962, Ser. No.. 245,233 2 Claims. (Cl. 20G-59) Thisinvention relates to an improved lift tab for pressure sensitiveadhesive labels.

yIn the hot stamping machine art such as exemplilied by my prior PatentsNos. 2,996,000, 2,960,024 and others, a marking foil is utilized whichin general has a cellophane backing with one surface thereof having alayer of coloring material thereon. In use, heated type is brought intocontact with the backing causing the coloring material to transfer tothe item upon which it is desired to print. As such foil is used, it isreplaced by fresh foil. It is accepted practice to provide such foil inthe form of a roll. At the outer-end of the roll it is desirable to afxa label identifying the manufacturer and carrying necessaryinstructions. This label has a coating of adhesive which permits it tooverlap the end of the tape and secure same to the roll preventingunwinding thereof. When it is desired to use the roll, this label mustthen be removed.

It is an object of this invention to provide a ready means for removingthis label.

Still a further object of this invention is to provide such means whichwill releasably adhere to the foil and not become loosened or fold overuntil desired.

Other objects and advantages will be readily apparent from the followingdescription:

In the drawings:

FIGURE l is a perspective of a foil roll embodying this invention.

FIGURE 2 is a perspective of the label.

FIGURE 3 is a further perspective of the label.

FIGURE 4 is a section illustrating the roll with the lift tab and labelaxed.

FIGURE 5 is a view similar to FIGURE 4 with the lift tab pulled freefrom the roll.

FIGURE 6 is a similar view illustrating freeing of the lift tab.

FIGURE 7 is a side elevation of a master roll of stamping foil having amaster strip of continuous printed label material affixed thereto.

FIGURE 8 is a perspective of the roll of FIGURE 7 with the stripattached.

FIGURE 9 is a perspective of a single roll cut from the master roll.

FIGURE 10 is a diagrammatic view illustrating the cutting of individualrolls from the master roll.

FIGURE 11 is a perspective of a master strip of continuous printedmaterial with the uncoated lift tab strip allixed thereto.

A roll of hot stamping foil is designated 10 and its outer end 12. Alabel 14 has a pressure sensitive adhesive 16 on one side thereof and isaffixed to the roll so as to overlap end 12 thereof and preventunrolling thereof. Such label may also function to carry suitableinformation on its outer face.

At the beginning edge 17 of the label a lift tab 18 in the form of anarrow strip is aixed to the adhesive face of the label preventing itsadherence to the roll. This lift tab may be grasped to facilitateremoval of the label and also functions to indicate the desireddirection of removal beginning with the outer llap end of the foil rolland in the direction of winding of the foil.

3,190,443 Patented .lune 22, 1965 ice To prevent the lift tabs becomingprematurely free or folding back, it should be formed of a suitablematerial having an electrostatic attraction to the carrier strip orbacking 19 of the tape 10. An example of such lift tab material ispolyethylene terephthalate, commonly sold by Du Pont under the name ofMylar, which is tear-resistant and has a moderate electrostaticadherence to same material or cellophane of the backing. A suitablecoloring material forms the pigmented surface 20 of the foil.

The lift tab thus formed permits the protruding portion to be pushedback readily to the edge of pressure sensitive label 14 and removal ofsame in a direction tending to further wind the foil on the roll.

In the manufacture of such rolls a long strip of label material 22 hasmultiple indicia 24 printed on one face and an adhesive on the otherface. A relatively thin strip of the lift tab material 26 is allixed bysaid adhesive along one edge of the label material. (See FIGURE 1l.) Theexposed adhesive face is then applied to a master roll of foil 28 withthe lift tab at the beginning edge 30 of the label material. The masterthus formed is placed upon a mandril and cut into individual rolls (seeFIG- URE 9), between adjacent printed indicia on said label material.

While what hereinbefore has been described as the preferred embodimentof this invention, it is readily apparent that alterations andmodifications may be resorted to without departing from the scope ofthis invention and such alterations and modifications are intended to beincluded within the scope of the appended claims.

I claim:

1. A roll of foil for a roll leaf hot stamping machine comprising: arolled strip of cellophane backing having a pigmented surface thereon, alabel having one face thereof coated with a pressure sensitive adhesiveand overlapping the outer extremity of the foil roll to preventunravelling thereof, a `lift tab of non-adhesive material adhered to theadhesive of said label along the edge thereof overlying said roll andextending outwardly from said edge to prevent adherence of said edge tothe roll, said lift tab being of a plastic material having anelectrostatic attraction to said cellophane backing.

2. An article of the class described comprising: a master strip ofcontinuous printed label material having a pressure sensitive adhesivecoating on one face thereof, an uncoated strip of material attached toand extending from only one edge portion of the adhesive coated face andextending laterally outwardly from said edge to form a linger hold lifttab when said label material is applied over the end of a roll of foil,said uncoated strip being of a plastic material having electrostaticattraction for said foil.
